How to fix I/O blocking on Great Wall GW3300 512GB?

Every time I turned around to look into the fog, I'd get this slight screen tearing—absolutely lethal for the immersion in a horror game. Looking back, my Great Wall GW3300 512GB had less than 15% free space, which triggered the garbage collection way too often, sending disk latency swinging wildly between 35-50ms. I tried lowering the texture quality first, but the game looked like a pixelated mess, which was a total dealbreaker. I ended up forcing a system-level TRIM command and used an alignment tool to verify the 4K sector status. The startup logs showed scene load times plummeting from 18.2s to 11.5s. It wasn't a smooth ride—I actually got a disk write error during the TRIM process until I cleared 30GB of temp files. Now the drive stays between 42-48℃ and feels rock steady. After three rounds of scene switching, the drops are gone, and my RAM temps are holding at 58-63℃. No more jarring jumps.
